OOW's creative fun tournament for our clients and friends: 9 holes, the 9 iron only and dressed all in black.
Next tournament
provisionally Saturday, 16 October 2027
Golf can sometimes be frustrating and complicated. Dirty-9 is the exact opposite: a fun tournament for everyone – including those who rarely set foot on a course but love it all the same! Once a year we invite golf fanatics, our clients and friends to the dirtiest round of the season, and in the evening we all celebrate together at our office with the finest view over Berlin.
“Polish your 9 irons and get the black golf gear out of the wardrobe. It's going to get dirty!”
The Dirty-9 rules
9 holes.
We play a four-person scramble. One round of golf as a team.
Just one club – the 9 iron.
Black clothing and the Dirty-9 cap.
Have fun and make great memories!
Dirty-Niners travel light! All you bring is your 9 iron. The signature cap, bag and balls are on us.
Flirty-9 – your first flirt with golf
For everyone who has never held a golf club and has thought over the past few years: “I'd like to join in too.” Since 2026 there has been the Flirty-9 taster course for exactly that. You learn the basics on the driving range, compete in a putting contest, and anyone who wants to can then play a hole on the course with the coach.

Dirtiest questions
Do I need to be able to play golf?
All you need is a green card (Platzreife). Golf club membership is not required. Anyone who has never played can join the Flirty-9 taster course.
What is a Texas scramble?
All four players in the team tee off, then the team picks the best ball. Everyone plays again from there until the ball is holed. That way every good shot counts, and nobody has to be good on their own.
What do I need to bring?
For the tournament just your 9 iron; for the course nothing but comfortable clothes and trainers. The dress code is black or navy, suited to the weather. You'll get the cap, balls and a bag with an umbrella from us.
How much does it cost to take part?
50 euros, the same for the tournament and the taster course.
Where is it played?
At Golfclub Kallin.
Where is the party?
From 5 pm at our office, Torstraße 42, 10119 Berlin. There will be food, drinks, the putting play-off and the prize-giving.
